[PATCH] x86: rust: set rustc-abi=x86-softfloat on rustc>=1.86.0

by Alice Ryhl

When using Rust on the x86 architecture, we are currently using the unstable target.json feature to specify the compilation target. Rustc is going to change how softfloat is specified in the target.json file on x86, thus update generate_rust_target.rs to specify softfloat using the new option. Note that if you enable this parameter with a compiler that does not recognize it, then that triggers a warning but it does not break the build.

[PATCH] arm64: tegra: delete the Orin NX/Nano suspend key

by Ivy Huang

From: Ninad Malwade <nmalwade(a)nvidia.com> As per the Orin Nano Dev Kit schematic, GPIO_G.02 is not available on this device family. It should not be used at all on Orin NX/Nano. Having this unused pin mapped as the suspend key can lead to unpredictable behavior for low power modes. Orin NX/Nano uses GPIO_EE.04 as both a "power" button and a "suspend" button. However, we cannot have two gpio-keys mapped to the same GPIO. Therefore delete the "suspend" key.

[PATCH v3 1/2] seccomp: passthrough uretprobe systemcall without filtering

by Eyal Birger

When attaching uretprobes to processes running inside docker, the attached process is segfaulted when encountering the retprobe. The reason is that now that uretprobe is a system call the default seccomp filters in docker block it as they only allow a specific set of known syscalls. This is true for other userspace applications which use seccomp to control their syscall surface. Since uretprobe is a "kernel implementation detail" system call which is not used by userspace application code directly, it is impractical and there's very little point in forcing all userspace applications to explicitly allow it in order to avoid crashing tracked processes. Pass this systemcall through seccomp without depending on configuration. Note: uretprobe isn't supported in i386 and __NR_ia32_rt_tgsigqueueinfo uses the same number as __NR_uretprobe so the syscall isn't forced in the compat bitmap.

[PATCH 1/2] smb: client: change lease epoch type from unsigned int to __u16

by meetakshisetiyaoss＠gmail.com

From: Meetakshi Setiya <msetiya(a)microsoft.com> MS-SMB2 section 2.2.13.2.10 specifies that 'epoch' should be a 16-bit unsigned integer used to track lease state changes. Change the data type of all instances of 'epoch' from unsigned int to __u16. This simplifies the epoch change comparisons and makes the code more compliant with the protocol spec.
